Depends on the platform. For Linux, Windows and Solaris it's pure Ruby. For FreeBSD, HP-UX, OS X and other BSD flavors it's a C extension.

Thanks, that worked. For Windows it seems that specifying "--platform=mswin32" was enough to install the VC 6 version on my VC 8 Ruby.

Well, I'm kind of stuck then. I have pure Ruby versions that will work on a particular operating system, but aren't tied to any particular runtime, bit-ness, etc.

If there isn't any way to specify that with the Gem::Specification, I would argue that we need some way to do so. Or am I the only person in the world hitting this particular issue?

Thanks,

Dan

PS - Yes, I know I've brought this up before, so sorry if I'm beating the issue to death. If you want to see what I'm dealing with, take a look at the sys-proctable source and tell me how _you_ would bundle the gems.
